outdoor recreation refers to various recreational activities, closely associated with natural environments. wetlands are the ecosystems which provide numerous goods and services with economic values, not only to the local population living in their periphery but also to communities living outside wetland. furthermore, wetlands provide some opportunities and amenities for human society’s well-be...

Oh, I know all the arguments in its favour. It is natural (although how any human activity, in the context of modern, sophisticated, high-powered living, can be deemed truly 'natural' is beyond me?but that is another argument); it provides an excellent food for the baby; it provides psychological security for the baby; it provides sexual pleasure for the mother, and also and therefore psycholog...

Human error is a byproduct of the human activity and may results in random unintended events; they may have major consequences when it comes to delivery of medicine. Furthermore the causes of error in surgical practice are multifaceted and complex. This article aims to raise awareness for safety measures in the cardiac surgical room and briefly "touch upon" the human factors that could lead to ...

Although the details of New England’s history and current landscape conditions are unique, studies of the region underscore ecological themes that are common to many landscapes and ecosystems worldwide. In similar fashion, the region’s dynamic history raises challenges for conservationists and land managers that are shared by decision makers for any region that bears the legacies of environment...

Recent studies for a wide range of human activities such as email communication, Web browsing, and library visiting, have revealed the bursty nature of human activities. The distribution of inter-event times (IETs) between two consecutive human activities exhibits a heavy-tailed decay behavior and the oscillating pattern with a one-day period, reflective of the circadian pattern of human life. ...

Human plague has been a recurring public health threat in some villages in the Western Usambara Mountains, Tanzania, in the period between 1980 and 2004. Despite intensive past biological and medical research, the reasons for the plague outbreaks in the same set of villages remain unknown. Plague research needs to broaden its scope and formulate new hypotheses. This study was carried out to est...

The Arctic environment is undergoing changes due to climate shifts, receiving contaminants from distant sources and experiencing increased human activity. Climate change may alter microbial functioning by increasing growth rates and substrate use due to increased temperature. This may lead to changes of process rates and shifts in the structure of microbial communities. Biodiversity may increas...

Engel's biopsychosocial model, Cassell's promotion of the concept "person" in medical thinking and Pellegrino's and Thomasma's philosophy of medicine are attempts to widen current biomedical theory of disease and to approach medicine as a form of human activity in pursuit of healing. To develop this approach further we would like to propose activity theory as a possible means for understanding ...

Across large parts of the world, wildlife has to coexist with human activity in highly modified and fragmented landscapes. Combining concepts from population viability analysis and spatial reserve design, this study develops efficient quantitative methods for identifying conservation core areas at large, even national or continental scales. The proposed methods emphasize long-term population pe...
